GAS-BURNER FOR FLARE-LIGHTS.

Application filed March 30,

T 0 all whom it may concern:

Be it known that I, Cinemas Crrnnns the King of land, residing at London, in England, have invented certain new and useful Improvements in or Relating to- Gas-Burners for Flare-Lights, of which the following is a specification.

This invention relates to improvements in gas-burners and more particularly to those employed with flare lights burning, for example, acetylene gas.

One of the chief features of this invention is the employment of a needle valve arranged to project through the burner orities for the purpose of producing an annular flame.

Other features of this invention will be evident from the following description taken in connection with the accompanying drawings, in which Figure l is a section of a burner for a flare light constructeo according to one embodiment of this invention. Fig. 2 is a part end view of the same looking in the direction of the arrow X in Fig. 1 and showing the burner orifice. 3 is a section on the line cb in Fig. 1 looking in the direction of the arrow X and Fig. 4c is a section on the line a-Z) in Fig. 1 looking in the direction of the arrow X Like letters indicate like parts throughout the drawings.

Referring to the drawings, the burner comprises a body A cast or otherwise constructed having a vertical passage A through which the combustible passes from the supply pipe to a horizontal passage A At the end of the horizontal passage A a con ical orifice A is provided, the body A being continued beyond this orifice to form a shield or directing mouth A} surrounding the orifice. A solid needle valve B is adapted to fit into the orifice A and the end of this needle valve is of such length and is so shaped that it projects right through the orifice into the mouthpiece A By employing a needle valve which projects through the orifice A? as just described, the combustible issues in such a way as to give a ring of flame which is found to be particu larly suitable for use in a flare light. At the same time the advantage is obtained that the valve is self-cleaning, it being impossible for the orifice to become incrusted with any of the products of combustion. Further,

by employing a solid needle valve instead of a hollow one through which the combustible gases are led, the advantage is obtained that there are no holes in the needle valve which can become stopped up and prevent the proper operation of the burner. The needle valve is of slightly enlarged diameter at B and this portion is provided with a screw thread and screws into the body A as shown. The needle valve B is provided with a stufiing box and to form this the body A is provided with an externally threaded portion A on to which an internally threaded nut C screws. Upon the spindle of the needle valve B a collar D is pinned, this collar being within a recess A formed in the portion A of the body A. Loosely surrounding the spindle of the valve B-is a collar E adapted to fit in a recess in the end of the portion A of the body A. Between the collar E and the nut C suitable packing F is arranged. F or turning the spindle of the needle valve B a handle B is provided. The collar D serves to prevent the valve from being withdrawn beyond a certain point. A number of air holes A are provided in the body A, these air holes being arranged circumferentially with respect to the orifice A The mouth piece A is preferably threaded externally to receive a wing nut G between which and a suitable flange on the body A, a reflector H can be clamped.

Upon the threaded portion A of the body A is screwed a dial plate I, this dial being graduated to show the candle power of the light obtained for any particular position of the needle valve B with respect to the orifice A For indicating this candle power the handle B of the needle valve B is provided with a pointer J. The pointer J is provided with a circular base plate J having slots J 2 therein. The base plate J is attached to the handle B by screws K passing through the slots J By providing the slots J and screws K, the position of the pointer J can be varied relatively to the graduations on the scale of the dial plate I, thus permitting of adjustment to correct for the error which would otherwise be introduced as the surface of the needle valve B wears away.

In order to enable the burner to be turned horizontally in any desired direction without the necessity for moving the lamp standard, or equivalent which, in the case of an acetylene lamp would be the generator of the A suitable construction of such a swivel.

jointvis. hown. irnF 1, the burner. body A being connected by a screw collar L to a pipe L The pipe L is provided at its lower end with a flange L this pipe with the flange fitting into a. gland M. which is connected to the. source of. supply' of combustible. Surrounding the. pipe. L is a nut N adapted to screwv into theglandM and compress. packing O situated between the nut andthe flange L 'on' the pipe L Though. the burner has been shown and described as being arranged tov direct the flame horizontally, it is obvious that it might be so arranged thatthe flame is directed in any required direction;

It is obvious that various modifications may be made in the methods of'carrying this invention into effect, the construction described above being'given merelyby' way of example-V What I claim as-my invention and desire to secure by Letters Patent is 1. A burner of the character described provided with an external shoulder, a re fiector embracing the burner and engaging; the front of the shoulder, and a nut upon the burner for clampingthe reflector against the shoulder, said nut being movable forwardly from the burner, substantially as described.

2. A burner of the character described: having a valve-controlled jet orifice, an ex-- ternal shoulder, a reflector embracing the burner and engaging the front of the shoulder, and a nut fitted upon the burner and clamping the reflector against the;- shoulder, said nut being removable forwardly from the burner, substantially as described.

& A burner of the character described, having a. needle, valve. provided with a hand wheel, a dial, an index cotiperating with the dial. and. having a slotted disk, and screws passing through the slots into the hand wheel, the slots in the disk being arranged to permit adjustment of the index on the hand wheel about its axis as a center; substantially as described.

4. A burner of the character described having a needle valve provided with a hand wheel, a: dial, an indexcobperating with the dial and provided with an attaching plate applied to the hand wheel and having an arcuate slot therein concentric with the-center of the wheel, and a fastening passing through the slot and entering the wheel to adjustably connect the attaching plate-thereto, substantially as described.

5; A. burner of the character described, comprising a tubular body, a transverse partition in said body, a ct orifice through said partition, the front end of the tubular body forwardly of the partition forming a mouth piece, a series of perforations extending at an acute angle through the tubular body and the partition, said perforations surrounding the jet orifice and converging forwardly into the mouth piece, the front ends of the perforations being in substantially the same plane as the front end of the jet orifice, and a needle valve extending through the body and having a pointed terminal cobperating with the jet orifice; substantially as described,

In testimony whereof I have signed my name tothis specification in the presence of two subscribing witnesses.
